| Abstract: | Based on Missenard method that estimates liquid thermal conductivity under pressurization condition by look-up table,and using liquid thermal conductivity data in literature,a new calculation model for liquid thermal conductivity under pressure was obtained.The model was used to calculate the thermal conductivity for 18 liquid systems containing 313 data points under pressure.It shows that the overall average relative deviation between calculation and experiment is 3.08%;the calculation is satisfactory with... |
